Lamar's comments are very sensible.

I always change the SSH port to something conspicuously different. Every
server has a different and difficult to guess SSH port number with
access restricted to a few IP addresses.

Waste of time = all the time and energy required to clean-up after a
hacker's breech when a few seconds work selecting a different port could
make a beneficial improvement to security.
